A former spokesman for Ariz. Sen. John McCain's 2000 campaign, Harris also served as communications director for former Florida governor Jeb Bush and California Gov. Arnold Schwarzenegger. He replaces Linda Rozett, who was let go last week.

Harris will oversee a communications shop in flux. Spokeswoman Burson Snyder left the campaign last week, and was replaced with Jim Mills, a former Fox News producer on Capitol Hill.
